Re: Grib
Guys,
Thank you for your help and quick responses. I greatly appreciate it.
You might want to add some of this to your documentation, however.
It doesn't mention anything about GDS and that was my main guide for
setting LAS up.
Just a suggestion,

Hi Adam,
You and I had some e-correspondance back around December 21. You
wrote that you have GDS servers at nomads.ncdc.noaa.gov:9090 and
nomads.ncdc.noaa.gov:9091. The LAS documentation concerning adding
gridded data at http://ferret.pmel.noaa.gov/LASdoc/serve/cache/16.html
will guide you through the process of configuring LAS for these
datasets, just use the GDS OPeNDAP URL instead of a file name for the
dataset url attribute and for running addXml.pl

Adam,
The most straight forward way to use LAS with grib files is to use
some "middle-ware" to handle the translation from grib to netCDF
on-the-fly.
In my opinion the best tool for this job (there are certainly others)
is the GrADS Data Server (http://grads.iges.org/grads/gds/gds.html).
You install GrADS and GDS and configure GDS to serve your grib
files. Clients (like LAS) that want to interact with these data will
be able to do so using the netCDF API as if the files were actually
stored in netCDF even though they will remain in grib. There is some
overhead, but the process in efficient enough to work with LAS.

Hello,
I've been searching through the LAS documentation and I haven't
found any information on how to point LAS at grib files. The
documentation describes how to convert our grib files into NetCDF,
but with gigs of data that's not really possible.
Any suggestions?
